Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION The present invention relates to a method for replacing replacement elements of a filling nozzle of a rotary filling machine.

Conventional technology With the diversification of containers, the frequency of replacing filling nozzle valves has increased.However, when changing the filling nozzle in a conventional rotary filling machine, the filling machine is stopped and an operator replaces the filling nozzle. Currently, replaceable elements such as replaceable filling nozzles and pocket guides are replaced while moving around the area.

However, this method requires a lot of labor because it is necessary to carry the removed and installed elements each time, especially in recent years when molds have to be changed frequently and filling machines are large. In the current situation where more than 120 filling nozzles have to be replaced, the increase in labor is even more noticeable and the efficiency is extremely poor.

Structure of the Invention The present invention is intended to improve the deficiencies of the conventional stopping and changing method of filling machines. A lifter capable of supporting a replacement filling valve is placed on the container holder of the filling nozzle, and by raising and lowering the lifter, the replacement filling valve is sequentially replaced and the pocket guide is replaced. The gist is to exchange elements.

To specifically explain the embodiment of the present invention, the rotary filling machine 1 is rotated counterclockwise by a variable speed motor as seen in the plan view of FIG. The structure is such that a container supported by the container is filled with liquid from a filling nozzle 4 that moves up and down and can be delivered in a tangential direction.

The filling nozzle 4 includes a filling valve base 6 protruding from the filling tank 5, a replaceable filling valve 8 that can be attached to and detached from the filling valve base using a tightening attachment device 7, and a replaceable filling valve 8 that can be freely connected to and detached from the replaceable filling valve and used for filling. It consists of an elevating device 9 provided on the tank 5 and a pocket guide 11 detachably attached to the inside of the container holder 3 at a pocket guide fixing position 10. Replace the valve 8 and pocket guide 11 with ones of a size corresponding to the container.

In order to replace the replacement filling valve 8, the valve replacement lifter 12 is positioned and mounted on the container holder 3, and the valve mounting base 13 above the lifter 12 is
The replacement filling valve 8 mounted on the valve base 6 or the replacement filling valve 8' to be replaced is mounted and supported on the replacement filling valve 8 to be replaced with respect to the filling valve base 6. , 8' can be raised or lowered without any effort.

Further, at a predetermined position of the rotary filling machine 1, a pair of storage chambers 14, 14' for a replacement type filling valve and storage chambers 15, 15' for a pocket guide are provided in sequence along the direction of rotation, respectively. Warehouse 14 and container 15
A replacement filling valve 8' and a pocket guide 11' to be replaced are respectively accommodated in the container 14' and the container 15'.

Therefore, in the reshaping work, a worker removes the outside of the rotary filling machine 1 at the A position near the housing 14 and the housing 15, and installs it at the B position near the housing 14' and the housing 15'. each person on the valve mounting table 13
The operator prepares and positions the lifter 12 with a foot switch 16 for driving the lifter, rotates the filling machine 1 at a lower speed than the rotation speed for filling operation, and at position A, the operator places the lifter for valve replacement on the container pedestal 3. 12 and lift the lifter 12, and after supporting the replaceable filling valve 8 mounted on the filling valve base 6 on the valve mounting table 13, remove the tightening mounting device 7, and then lower the lifter 12. Then, the replaceable filling valve 8 is removed from the valve mounting table 13 and stored in the housing 14, and the pocket guide 11 is also moved to the pocket guide fixing position 10.
The container is removed from the container holder 3 and stored in the container 15. In this manner, the removal operator removes the replaceable filling valve 8 and the pocket guide 11, which are moved sequentially.

On the other hand, the operator installing container 1 at position B
Pocket guide 1 to be newly installed from 5'
1' to the container holder 3 at the pocket guide fixing position 10.
After installing the lifter 12, position and place the lifter 12 on the container holder 3, take out a new replacement filling valve 8' from the container 14', install it on the valve holder 13 of the lifter 12, raise it, and fill it. It is fitted onto the valve base 6 and attached using the tightening attachment device 7, and then the lifter 12 is lowered. Thereafter, a replaceable filling valve 8' and a pocket guide 11' are respectively attached to each filling valve base 6 that rotates in this manner.

Although the rotation of the filling machine 1 in the above embodiment has been described as continuous rotation, intermittent rotation may also be used, and the rotation speed is such that the rotation speed is low enough to allow replacement at a slower rate than during filling. , it is preferable to rotate the filling nozzle 4 at a rate of 5 minutes or less per pitch.

Effects of the Invention The present invention utilizes the rotational action of a rotary filling machine for filling, and sequentially moves at a fixed position while maintaining the speed slower than the rotational action for filling so that replacement operations can be performed. Filling elements such as the filling valve and pocket guide can be replaced according to the size of the container, eliminating the need for workers to carry and move the filling elements each time, which is required in the conventional stop-replacement system. Efficiently changing the shape of the filling element of the filling nozzle with extremely little effort and time without requiring any special means or equipment such as moving the filling action guide etc. for replacement. In addition, the new and old interchangeable filling valves to be replaced can be moved up and down with a lifter to be attached to and detached from the valve base, so the attachment and detachment operations are easy and labor is further reduced.
